Description
Technical Field
The invention relates to the technical field of secondary lining vault grouting, in particular to an anti-hollowing multi-angle grouting device for a tunnel secondary lining vault.
Background
The secondary lining vault is a common construction defect of mountain tunnels. The secondary lining of the tunnel is an arch concrete structure, and concrete is generally cast in situ by adopting a steel template trolley. Because the concrete is poured from bottom to top, and the sealing effect of the steel template is added, the vault of the tunnel is not easy to pour compactly. The reason for causing the lining vault to be hollow comprises insufficient pumping pressure, poor concrete fluidity, over-tight paving and hanging of waterproof boards and the like, and the lining vault is very easy to be hollow due to the extremely many factors involved. In order to avoid the terminal from being emptied in the pouring process, the arch top pouring compactness is dynamically monitored in the pouring process of lining concrete, and grout is timely filled in the non-compact part. In the aspect of monitoring, due to the fact that a steel formwork blocks when pouring, people cannot see whether the gap exists and the local part of the gap, at present, a relatively advanced method is that a distributed compaction sensor is arranged between a waterproof plate and a primary support, and the compaction states of different longitudinal positions can be monitored. In the aspect of grout supplement, the currently common method is to arrange radial grouting pipes on a lining trolley at intervals along the longitudinal direction of a tunnel for grout supplement, and the method for grout supplement by the aid of the embedded grouting pipes has certain problems: firstly, the number of grouting pipes is limited and the positions are fixed, so that on one hand, the whole vault area cannot be covered, and the grout supplementing width is insufficient, and on the other hand, the grouting pipes cannot radially extend into a specified void area to accurately supplement grout; secondly, the grouting pipe is left in the secondary lining after the grout is supplemented, the strength of the supplemented grout is affected, and as the service time is prolonged, cracks can be generated on the contact surface between the grouting pipe and the secondary lining concrete, so that water leakage and disease are caused.
